619.03 Construction Requirements

619.03.1 Definitions

The following definitions apply to the signing work in the contract.

619.03.2 Design Calculations and Shop Drawings

The Department will furnish the sign design calculations for the project at the pre- construction conference. The sign design calculations will only be provided for signs not listed within the MUTCD-Standard Highway Signs . Submit Contractor approved (stamped) shop drawings and welding procedures for sign bridges, and overhead cantilever sign structures. After the structural steel shop drawings and welding procedures have been reviewed and checked by the Department, all required corrections will be returned to the Contractor who must make the corrections and re-submit the corrected drawings and welding procedures for final review and approval within 15 business days. All final drawings must be stamped “Approved” by the Department before fabrication begins. Submit shop drawings and welding procedures at one time in a complete package for the Department’s initial and subsequent reviews. Individual parts of the submittals will not be accepted for review.

619.03.3 Fabrication and Erection

Install bolted connections in accordance with Subsections 556.03.8 and 703.04.5 . Fabricate the signs and sign legends before delivery to the project, except for signs too large to transport in one piece to the project. Fabricate all signs using the hole spacing specified in the FHWA Standard Highway Signs book or the Detailed Drawings. The lengths of poles and steel posts shown in the contract are estimated lengths. The Project Manager will furnish the required length of each pole and steel post prior to fabrication. Locate and erect signs as specified or directed. The Project Manager may change sign locations due to field conditions. Erect signs so the sign face is vertical and aligned as specified. Sign supports must not project above the sign faces. When necessary, use full width piano hinges for all folding signs. Ensure that hinges are capable of withstanding normal dead and live loads applied and be securely fastened by bolting or riveting to the sign. The hinge must meet the requirements of Subsection 704.01.9 . 2020 EDITION V5.1 SIGNS AND DELINEATORS – 619 619-3 After the sign is installed and adjustments are made, jam the threads of the mounting bolts, or use vandal resistant nuts for ground-mounted sign faces 25 square feet (2.3 m2) and smaller. The specified foundation depth for timber posts and poles is a minimum depth. Field cut the poles to the correct length or bury the extra length to provide the specified mounting. Backfill foundation holes for timber posts and poles as follows: • Combine and thoroughly mix the material excavated from the foundation with cement using a mix ratio of 10 parts excavated material to 1 part cement. • Do not mix in the hole. Add water to make the soil-cement mixture. • Place the sign post or pole in the hole without the sign attached. • Backfill the hole with the soil-cement mixture in 8-inch (200 mm) maximum lifts. • Compact each lift by hand tamping or using mechanical methods. • Allow the foundation to cure for 7 days before mounting the sign face to the support. Foundation holes for wooden sign supports may be backfilled with CLSM using the specifications for constructing foundations for steel sign posts as follows. Construct foundations for steel sign posts with Class General concrete in accordance with Section 551. Finish foundations flush with the adjacent surfaces. Signs may be post mounted after the concrete has set 72 hours. Weld metal joints and post breaks in accordance with Sections 556 and 624.

619.03.4 Inspection

The completed signs will be inspected on the project before they are installed. Defects including but not limited to cracks, tears, splits, crazing, gouges or curled edges of the background sheeting or legend are cause for rejecting the sign. The installed signs will be inspected at night for nighttime retro-reflectivity and readability. Adjust signs exhibiting specular reflection, as directed.

619.03.5 Sheet Aluminum Overlay

Meet the contract requirements for sheet aluminum overlays. Install the sign legend and other components plumb and level. Match the color, shade, and type of existing reflective sheeting used as a background for partial overlays. Fully cover the existing legend and symbols with partial overlay backgrounds. Match the size of the existing sign with complete overlay backgrounds.

619.03.6 Replace, Reuse Sign Face, and Reset

Use new materials in accordance with Section 704 for that required over and above those materials salvaged from signs to be reset or reused. Install breakaway devices on existing posts when specified. Reset signs in accordance with Subsection 619.03.3. Repair or replace all Contractor sign damage resulting from dismantling, moving, and resetting at Contractor expense. With no exception, remount or reset within one hour all removed warning, regulatory signs, and route markers. Re-install guide signs within 5 hours and only during daylight hours. Re- display warning, regulatory, and guide signs by dusk. Erect the new sign and support before removing the existing sign being replaced. Do not display conflicting signs together. Do not obscure existing signs when placing new signs. Re-erect existing multiple support signs to be removed and reset using the original post spacing. 619 – SIGNS AND DELINEATORS 2020 EDITION V5.1 619-4

619.03.7 Installation Date Tags and Route Markers

Install date tags and route identification tags on all highway signs before final acceptance. Meet the contract requirements for design, color, and installation.

619.03.8 Delineators

Furnish and install new delineators at the locations specified and marked by the Project Manager. Remove delineators conflicting with new construction as specified.

619.04 Method of Measurement

619.04.1 Aluminum Signs

Aluminum sheet and aluminum sheet increment are measured by the square foot (m2) of sign face.

619.04.2 Metal Posts

Metal posts are measured by the pound (kg). The pay weight is calculated by multiplying the nominal weight per foot (m) by the installed length of each post as noted in the Detailed Drawings. When ap plicable, the weight of the anchor sleeve will be added to the post weight. If there is no breakaway system bid item, include with the post weight the weight of the base plates, fuse plate, and stub post or anchor sleeve including the embedment length.

619.04.3 Treated Timber Poles and Posts

Treated timber poles and posts are measured by the foot (m) in even 2-foot (610 mm) increments. When the measurement falls between increments, the measured length for payment is the next higher 2-foot (610 mm) increment.

619.04.4 Delineators

Delineators of each type specified are measured by the unit and include the reflector, mounting hardware, post, and snow pole, if applicable, complete in place. Removal of existing delineators is not measured for payment.

619.04.5 Flexible Delineators

Flexible delineators of each type specified are measured by the unit.

619.04.6 Reset Signs

The reset of guide, warning, regulatory, and route marker signs is measured by the unit for each sign removed and reset in a new location. Sign groups of 2 or more signs mounted on a single support or multiple supports are measured as a single sign. When signs designated as “Reset” require new supports to achieve the proper mounting height, include the costs of the supports in the cost of reset signs. When there is not a bid item in the contract for reset sign, this work is incidental to other items of the contract.

619.04.7 Remove Signs

The removal of guide, warning, regulatory, and route marker signs is measured by the unit for each sign removed including supports. Sign groups of 2 or more signs mounted on a single support or multiple supports are measured as a single sign.

619.04.8 Replace Signs

New materials for signs designated “Replace” are measured in accordance with Subsections

619.04 1, 619.04.2, and 619.04.3.

Removal of existing signs designated “Replace” are measured in accordance with Subsection 619.04.7. 619 – SIGNS AND DELINEATORS 2020 EDITION V5.1 619-6 New materials for signs designated “Replace Sign Face” are measured in accordance with Subsection 619.04.1.

619.04.9 Reuse Sign Face

New material for supports for signs designated “Reuse Sign Face” is measured in accordance with Subsections 619.04.2 and 619.04.3. Removal of existing signs designated “Reuse” is measured in accordance with Subsection
